A review on protection schemes and coordination techniques in microgrid system

A protection scheme emures that shod-circuit event is detected and fault is cleared by the protective devices and protective coordination is to ensure that the correct device operates to isolate the faulty parts. Combination of these algorithms affirms the successful operation of protective devices in a distribution system. Significant changes occur in a distribution system when there is a high proliferation of distributed generation in the system. This results in the development of different approaches for tackling the protection issues in a microgrid distribution system. This study presents a review on the available protection schemes and coordnation techniques used for addressing the protection issues in a microgrid distribution system. The various protection schemes and coordination techniques applied for microgrid protection are dscussed in terms of implementation methods, modes of operation, types of distributed generations, availability of communication links, and lastly their advantages and disadvantages.
